Specification of Letters Patent.

Patented June 8, 1915.

Application filed October 31, 1914. Serial No. 869,619.

To all whom it may concern:

Be it known that I, FRANK W. JAcoUEs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Safety-Envelops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to safety envelops, and one of the principal objects of the invention is to provide reliable and efiicient means of simple construction which will prevent the envelop from being opened by a an unauthorized person, and which if tampered with or steamed Will indicate that some unauthorized person has been endeavoring to secure the contents of the envelop.

Still another object of the invention is to provide a safety envelop having a doubled seal which cannot be detached for opening the envelop without mutilation and without indicating to the authorized addressee that the envelop has been tampered with.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which,

Figure l is a plan view of the blank from which the envelop is made, Fig. 2 is a view looking at the rear side of the envelop with the two side flaps folded together, Fig. 3 is a rear elevation showing the two side flaps folded together and the bottom flap folded upwardly, Fig. 4 is a rear side elevation of the envelop in position for sealing, Fig. 5 is a front elevation of the envelop when sealed, and Fig. 6 is a sectional view taken centrally through the sealed envelop and made on a larger scale, than the other figures.

Referring to the drawings, the numeral 1 designates the body of the envelop, and 2 are the side flaps, said side flaps being substantially rectangular and provided upon their upper edges with projecting tongues 3. The upper edges of the side. flaps 2 are also cut away on the inclined line 4 and provided with a shoulder 5. The bottom flap 6 is provided with a projecting neck 7 and a partially round head 8. The sealing flap 9 is provided with an aperture 10 which is preferably rectangular in-form, said aperture being formed at the base of thesealing flap 9. The side flaps 2 are folded inward on the lines a and the bottom flap 6 is folded upward on the dotted lines I), while the sealing flap 9 is folded upon the line 0 after the head 8 has been passed through the aperture 10, as will be hereinafter described.

In bending or folding the parts of the envelop side members 2 are folded inward, and

the tongues 3 and the over-lapping portions 2 are gummed, and when the flaps are united and the tongues 3 are moistened, the lower flap 6 is folded upward on the line (Z and the tongues 3 are united to the neck portion 7 of the lower flap. A tongue 2 at the lower corner of one of the side flaps 2 is gummed and secured to the other side flap when folded. For sealing the envelop the head 8 is passed through the aperture lO and is provided with a gummed surface to stick it down upon the face of the envelop as shown in Fig. 5 of the drawing.

Applied preferably to the outer side of the head 8 is a small quantity'of indelible lead and fish-glue 11 and at three points on the sealing flap 9 may be applied ,a small quantity of either indelible lead, fish-glue or other substance 12 and 13,,the purpose of which is to indicate when the envelop has been steamed or tampered with by changing the appearance of these materials upon the face of the sealing flap. Any suitable material for the purpose may be used. 2 7

Various changes in the details of construction may be resorted to without departing from the spirit and scope of the invention as defined in the claim.

What is claimed is A safety envelop comprising a body portion, sideflaps folded inwardly, said side flaps having upwardly projecting gummed tongues, a lower flap provided with a'neck and an enlarged head, and a sealing flap provided with an aperture through which said head is adapted to extend said tongues In testimony whereof I aflix my signabeing sealed to the neck of the lower flap, ture in presence of two Witnesses.
